Le futur simple
You already have one future: futur proche (je vais manger — going to eat). Today's tense is the futur simple — a single word, no helper verb. Je mangerai = I will eat. Same idea, different feel: futur proche is everyday spoken French; futur simple is more formal, written, or distant — predictions, promises, schedules, weather forecasts, news. Both are correct; you'll mix them like an English speaker mixes 'I'm going to eat' and 'I'll eat'.
How to form it — the infinitive IS the stem
Best news in French grammar: for almost every verb, the futur simple stem is just the infinitive. Then you add the endings: -ai, -as, -a, -ons, -ez, -ont. That's it. parler → je parlerai, tu parleras, il parlera, nous parlerons, vous parlerez, ils parleront. Notice the endings sound exactly like the present of avoir (ai, as, a, avons, avez, ont) — that's the historical link, and a useful memory hook.
-IR and -RE verbs
-ir verbs keep the whole infinitive: finir → je finirai, tu finiras, il finira, nous finirons, vous finirez, ils finiront. partir → je partirai, tu partiras. dormir → je dormirai. -re verbs drop the final e before adding endings: prendre → je prendrai, tu prendras, il prendra, nous prendrons, vous prendrez, ils prendront. écrire → j'écrirai. lire → je lirai.
Common irregular stems — memorize these
About a dozen common verbs use a special stem (still with the same endings). The big ones: avoir → aur- (j'aurai = I'll have). être → ser- (je serai = I'll be). aller → ir- (j'irai = I'll go). faire → fer- (je ferai = I'll do/make). pouvoir → pourr- (je pourrai = I'll be able to). savoir → saur- (je saurai = I'll know). venir → viendr- (je viendrai = I'll come). voir → verr- (je verrai = I'll see). vouloir → voudr- (je voudrai = I'll want). devoir → devr- (je devrai = I'll have to). falloir → faudra (il faudra = it will be necessary).
Futur simple vs futur proche
Both translate to English 'will' / 'going to'. The split is a matter of register and distance. Futur proche = imminent, conversational, plans you've already made: Je vais voir Marie ce soir (I'm going to see Marie tonight). Futur simple = farther off, more formal, predictions, promises, scheduled events: L'année prochaine, je voyagerai en Asie (next year I will travel to Asia). Demain, il fera beau (tomorrow it will be nice — weather forecast). Je t'aimerai toujours (I will love you forever — promise). In casual speech, French uses futur proche for almost everything close in time.
Negation and questions
Both wrappers work the same as everywhere. Negative: ne + verb + pas. Je ne viendrai pas = I won't come. Elle ne sera pas là = she won't be there. Questions: rising tone (Tu viendras?), est-ce que (Est-ce que tu viendras?), or inversion (Viendras-tu?). Quand est-ce que vous partirez? = When will you leave? Que ferons-nous? = What will we do?
After quand and si — a French quirk
Two important wiring rules. After quand (when) referring to a future event, French uses futur simple where English uses present: Quand je serai grand, je serai médecin = When I'm grown up, I'll be a doctor (literally 'when I will be grown up'). After si (if), the opposite — French uses present, like English: Si tu viens, je serai content = If you come, I'll be happy. Memorize the pair: quand + future, si + present.
